More on Spica

Continuing from the last post on star and constellation names, in addition to the use of Spica at an ancient epoch in connection with a determining latitude, it has also been suggested earlier that the prime meridian was associated with the star.

According to certain Indian and Muslim (al-Balkhi) schools of astronomy, the eastern city of Yamakoti marked the prime meridian.

Yamakoti, Lanka or Ujjain, Romakapura and Siddhapura were placed in order from East to West at quadrants from each other by Indian astronomers supposedly forming a circle around the earth, with Siddhapura in the Western Hemisphere. However, it is clear that these four points instead only delineate the known world, or about half the globe at the time, as the Muslim writer Al-Biruni notes:

How the Hindus came to suppose the existence of Siddhapura I do not know, for they believe, like ourselves, that behind the inhabited half-circle there is nothing but unnavigable seas.

Earlier in this blog, we noted that Romakapura ('Romaka City') was associated with the astronomy of Ptolemy and other Alexandrian astronomers and therefore Romaka is likely Alexandria rather than Rome (as suggested by some scholars). The city of Ujjain, famed for its astronomical observatory, was located at about 75.5° East longitude in India. Therefore, Romakapura and Ujjain were located about 45 degrees or three hours from each other.

Now, Siddhapura, the city of the Siddhas, or perfected ones, appears related to the Fortunate Isles of Ptolemy, used by the latter as the prime meridian. The Fortunate Isles were the blessed islands, the paradise of the heroes in Western mythology. It seems here that the Siddhas would correspond in Indian terms to the Greek Heros. Now, Ptolemy's Fortunate Isles are generally associated with the area around the Canary Islands or roughly around 15° West longitude and thus about three hours West of Alexandria.

Yamakoti, a city famed for its gold, is easily linked with Suvarnadvipa, the "Gold Island" and would be placed then for consistency three hours to the East of Ujjain. Here is a map of our suggested locations for these Indian meridians.

Ptolemy's map of the world was derived from that of Marinus, a geographer who lived at the port city of Tyre in Lebanon. Marinus claimed to have gleaned his information from travelers like Diogenes, an Indian who ventured to Rhapta on the African coast, and Alexander, a Macedonian who obtained information on the sea voyage from the the Golden Chersonese (Malaya Peninsula) to Cattigara, the furthest port to the East in Greek geography.

Cattigara was said to be a great emporium of the Sinae. While it is tempting to connect the Sinae with the placename "Chin" and similar latter cognates for China, Marinus and Ptolemy use the terms Thinae and Seres to describe most of what constituted China at the time. As the countries of the Sinae were said to cover the area along the sea (Gulf of Sinae) southeast of India extra Gangem, it would describe the extreme southeast of modern Southeast Asia.

The emporium was placed by Marinus as a few days sailing to the southeast of Zaba, although Ptolemy thinks it was many days from Zaba. The latter market city is normally linked with the kingdom of Champa, although some think it may have been on the east coast of the Malaya Peninsula. Historically though, Champa may have been founded later than Marinus time in the early part of the 2nd century, but the datings here are murky. The country of Linyi, the Chinese name for the latter kingdom of Champa, arises in about 192 CE, but there are indications of earlier antecedents south of the Chinese sphere of influence.


Marinus' Grid System and the Chinese

Marinus of Tyre was the first person in the West to use a grid system marking latitudes and longitudes. However, he was preceded in China where geographers had used such a system since the Qin Dynasty, with particular developments during the Han Dynasty.

Joseph Needham notes that while the grid system in the West was an interrupted development, it continued to be used by the Chinese throughout their history into modern times.

One of Marinus most important informants was a Syrian known as Maes Titianus, who was said to have conducted trade in silk with the Seres (Chinese). It appears that Marinus may have learned about the Chinese grid system from Maes Titianus or possibly from Alexander the Macedonian.

Zou Yan (250 BCE) divided the earth into nine continents through which the Sun passed on its daily rotation. A massive district known as the Red District with China located in the southeast corner appears to describe something similar to the inhabited world of Marinus and that of the ancient Indian astronomers. This district is described as 28,000 li from East to West and 26,000 li from North to South. During this period it is thought that the li represented about a third of a mile, so the dimensions would be about 9,333 miles by 8,666 miles. Zou Yan, though, somewhat like the Hindu astronomers in relation to the mythical circular continents around Meru, apparently inflates the size of the rest of the world in order to conform to traditional cosmology.

The Red District was divided into a three by three "magic square," of nine squares, with each of these nine squares again divided into into another magic square of nine squares. So that from East to West, the district was divided into nine divisions or hours.

Of course, if we accept my identification of Yamakoti and the other three Indian astronomical cities, the total distance between them is in fact nine hours consisting of 135 degrees.

Marinus, however, made the distance from the Fortunate Isles to Cattigara into 15 hours of 225 degrees, while Ptolemy suggested instead 12 hours of 180 degrees. It should be noted that the remaining "uninhabited" area of the world according to Marinus estimate was in fact nine hours of 135 degrees, so maybe there was some miscommunication along the way.

Now getting to the connection of geography with the star Spica, the Huananzi (2nd century BCE) divides the sky into nine fields. For the Daoists, the nine divisions of Heaven corresponded to the nine divisions of Earth. Zou Yan describes the Sun traveling across the nine continents in a day just as it transversed the ecliptic through the year.

The first field of Heaven is led by the asterism Kio, containing the star Spica. The first part of the world, the beginning of the East in Chinese thought, is the region of the Fusang Tree.

The Sun rises in Yanggu (Bright Valley),
Bathes in the Xian Pool,
And rests in the Fusang Tree.
This is called the Dawn Light.
Ascending the Fusang, it commences its journey...
...the Sun travels over the nine continents, and seven resting places.

-- Huananzi: "The Treatise on the Patterns of Heaven"

So, it would appear that Fusang, the beginning of the East for the Chinese, was the limit of the East, or Cattigara, of the Greeks. For certain Indian and Muslim schools of astronomy, Yamakoti also served as the starting point.

Marinus estimated the distance between the Fortunate Isles and Cattigara at 11,250 miles while Ptolemy gave the distance as 9,000 miles as both thought the degree equaled 50 miles at the equator. Again Zou Yan's estimate is about 9,333 miles depending on the exact equation of the li, while the actual distance using our identification of these locations is 8,100 miles.

Ptolemy locates Cattigara at 177° East and 8° 25' South, but his coordinates in this region are overextended in both the eastern and southern directions. Later, during medieval times and the early part of the Renaissance, European maps followed this tradition placing mainland Southeast Asia south of the equator and the coast of China near or beyond 180° East longitude.

When Magellan neared the islands of what is now known as the Philippines he was steering for Cattigara according to shipmate Pigafetta, apparently recognizing Ptolemy's errors in longitude and latitude.

In conclusion, the star Spica was placed at the beginning of the nine fields of Heaven just as the Fusang region was at the head of the nine continents, in the font of the East. The star served to mark the start of the year when the Zenith Moon passed nearest during the year, with the zenith located directly over Tanggu (Yanggu) and the Fusang Tree. This latter location has basically the same identity, at least geographically, with Yamakoti and Cattigara. Marinus of Tyre may have heard of the Chinese grid system together with its starting point from Maes Titianus or Alexander the Macedonian, and simply reversed the order of reference. The Indian astronomers may have heard of the system from Sakadvipa migrants, who had established themselves in India during the country's golden age of astronomy.

Dog Star (Glossary)

The dog star has through the ages been associated with Sirius and/or less frequently the planet Venus.

The name of Sirius probably is derived from the Egyptian word seir meaning "prince," and related also to Hebrew sar. Another possibility is that the word comes from the Greek form for Osiris, the Egyptian god of the underworld.

The star is the brightest in the heavens and was called Kasista "Leader" by the ancient Akkadians. The Persians knew it likewise as Tistar "Chieftain" or Zeeb "Leader."

It was pictured in cultures throughout the world as a dog or wolf situated in the southern sky and associated with the hot or "dog days" of summer.

Sirius is also often connected with the image of a hunter. Among the Sumerians, Ninurta, the hunter, and husband of the dog goddess Bau (Gula), was linked with Sirius, while his wife had Venus associations. Later, when Inanna absorbs Bau's attributes she is likewise viewed as a huntress with links both to Venus and Sirius.

In Greek myth, Sirius formed the head of the hunter Orion's dog, the constellation Canis Major. According to Monier-Williams, the dog star was known among Hindus as Lubdhaka and Mrgavyadha both meaning "hunter" and referring to the god Siva or Rudra.

Another association of Sirius connects the star with the Milky Way, known often as the "Way of Souls" or the "Way of the Dog/Wolf." In this sense, Sirius is viewed as one or more dogs or wolves guarding the path taken by departed souls.

In ancient Egypt, the heliacal rising of Sirius was central to the yearly calendar. Sirius and Orion are personified respectively by the deities Sopdet and Sah, who are in turn manifestations of Isis and Osiris. Sopdet and Sah beget Sopdu, who is the manifestation of Horus, the son of Isis and Osiris, and the patron deity of Egyptian royalty. Sopdet is sometimes portrayed as a large dog, or as riding side-saddle on a dog (during the Roman period).

When the Sun and Moon conjoined at the start of the Egyptian New Year a festival known as the "sacred marriage" was celebrated. This may relate to the Pyramid Texts which state that Pharaoh unites with Isis in a form of hieros gamos bringing forth Horus-Sopdu. In another passage, the royal-divine union is said to beget the Morning Star, and thus may connect Venus with Horus.

Among the Sumerians, the sacred marriage took place between the priest-king and Inanna, the latter probably represented by the Lukur priestess, who was in turn linked with the daughters of dog-headed Bau. Inanna again has as her planet Venus and Sirius as one of her fixed stars. The king during this ritual stands for Dumuzi, the husband of Inanna, and every year near the rising of Sirius in the summer, the Kelabim or dog priests of Dumuzi (Tammuz) held rites for the god.

Adonis had similar rites, and Carl Kerenyi believes that the orgia festivals celebrated in honor of Dionysos were also linked with the Sirius cycle.

Further to the east we find numerous myths of the marriage of a dog to a goddess or queen in the totemic histories of numerous peoples. Especially in Central Asia, South China, Southeast Asia and the Pacific the concept of part-dog or wolf ancestry is prevalent. From Assam in the West to Mongolia in the North and Java in the South, eastward to New Guinea and other Pacific isles in Oceania and northward again to the Ryukus and Bering Sea, the sacred dog-human marriage motif is found.

David Gordon White in Myths of the Dog-Man discusses the motif found among the Chinese, Hmong-Mien and Southeast Asian peoples of a heavenly dog who comes to earth following catastrophic floods bringing the gift of rice agriculture. These resemble closely the Kapampangan tales of Tala who rescues the flooded inhabitants of Central Luzon by teaching them riziculture. White mentions a "tradition, dating from the Shang dynasty, that connects a dog with the ancient rice god Shang-ti, and a Ch'in and Han period sacrifice called the lei (a term for which the Chinese characters are "dog," "rice," and "head") that involved the offerings of dog's flesh and rice, by which a dismembered Shang-ti was ritually reintegrated and resurrected."

Shang-ti becomes associated with T'ien (Heaven) during the Zhou (Chou) dynasty and the Shih-chi states that the god in the form of the "Ti-Dog" was the ancestor of the Hou Chih and T'ai peoples.

Although Sirius (known as the Heavenly Wolf in China) is not mentioned in these legends, the idea of a heavenly dog coming after the summer floods indeed could represent a link with the dog Star. The heliacal rising of Sirius during the summer heralds the flooding season in the monsoon climate region. The descent of Sirius or Venus from Heaven in the form of a dog bringing agriculture and uniting in divine marriage all fit in the Sirius myth pattern. The flooding of the Nile after the rising of Sirius was essential to good harvests in ancient Egypt.

The image of Phan Hu descending from Heaven and swimming across the flooded earth with a rice plant in his mouth, to later marry the Chinese emperor's daughter and father the Yao people is an ideal form of the Eastern myth.

While various explanations have been given for the canine attributes bestowed to the star Sirius, the link with a culture-bearing ancestor is the one proposed here. In this sense, the heliacal rising of Sirius would herald the advent of the canine hero linked in this case with the cataclysmic eruption of the cosmic mountain.

In ancient symbology, this involved the Sun and Moon, not simply conjunct as in the Egyptian New Year festival, but in solar eclipse represented by the Crescent Sun. Venus in inferior conjunction or transit is represented as a star in the center or next to the Crescent Sun. These celestial bodies should be placed above or emerging from a mountain, hill, mound, stupa, triangle, pyramid, person's head or some other symbol of the cosmic axis.

In some cases, one can also see to the left of these symbols another star or stellar symbol that should be taken as representing Sirius. Left in this case means to the south as ideally the celestial configuration should be in the West, the direction of Pinatubo.
